kernel: 5.10: Backport pending Armada 3720 comphy patches
Backport 5 pending patches [1] for Armada 3720 comphy driver and one
patch for device tree, applied to mvebu-dt64, but pending to appear in
Linus' tree [2].
These patches makes the driver work correctly even with older, buggy
versions of TF-A firmware.
